From 25513619dbf1a7c4daaa32e841d8f560d0d18bf5 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Wed, 6 May 2009 17:18:57 +0000 Subject: * procfs.c (procfs_insert_watchpoint, procfs_remove_watchpoint) (procfs_region_ok_for_hw_watchpoint, procfs_use_watchpoints): New functions. (procfs_stopped_by_watchpoint): Made static, ptid argument removed. (_initialize_procfs): Register new watchpoint related target functions. * config/i386/nm-i386sol2.h (TARGET_CAN_USE_HARDWARE_WATCHPOINT) (TARGET_REGION_SIZE_OK_FOR_HW_WATCHPOINT, STOPPED_BY_WATCHPOINT) (HAVE_CONTINUABLE_WATCHPOINT): Delete. (target_insert_watchpoint, target_remove_watchpoint): Delete. (procfs_stopped_by_watchpoint, procfs_set_watchpoint): Delete declarations. * config/mips/nm-irix5.h (STOPPED_BY_WATCHPOINT) (TARGET_REGION_SIZE_OK_FOR_HW_WATCHPOINT): Delete. (target_insert_watchpoint, target_remove_watchpoint): Delete. (procfs_stopped_by_watchpoint, procfs_set_watchpoint): Delete declarations. * config/sparc/nm-sol2.h (TARGET_REGION_SIZE_OK_FOR_HW_WATCHPOINT) (HAVE_CONTINUABLE_WATCHPOINT, STOPPED_BY_WATCHPOINT): Delete. (target_insert_watchpoint, target_remove_watchpoint): Delete. (procfs_stopped_by_watchpoint, procfs_set_watchpoint): Delete declarations. --- gdb/config/i386/nm-i386sol2.h | 24 ------------------------ gdb/config/mips/nm-irix5.h | 23 ----------------------- gdb/config/sparc/nm-sol2.h | 25 ------------------------- 3 files changed, 72 deletions(-) (limited to 'gdb/config') diff --git a/gdb/config/i386/nm-i386sol2.h b/gdb/config/i386/nm-i386sol2.h index 5ac917e..ab8ff19 100644 --- a/gdb/config/i386/nm-i386sol2.h +++ b/gdb/config/i386/nm-i386sol2.h @@ -20,17 +20,6 @@ #define TARGET_HAS_HARDWARE_WATCHPOINTS -/* The man page for proc4 on solaris 6 and 7 says that the system - can support "thousands" of hardware watchpoints, but gives no - method for finding out how many.
